This application takes photos or video from an external USB camera. It is a very basic application for operating USB webcams. It can adjust camera parameters (Brightness, Gamma, Hue, Contrast, Saturation and Sharpness). It should work for most Android smart cellphones or tablets. But, this application will not work for some models (for example, Samsung of android 5.1.1). The best tool to test if your mobile device supports USB camera is a free app available at Google Play Store, USB Camera Detector (https://play.google.com/store/apps/details?id=net.shop1234.androidthings.usbenum). Photos are stored at Main Storage/DCIM/usbcamera, videos at Main Storage/Movies/usbcamera
